The common terms of bearing

1 technical personnel commentator bearing commonly used terms. Dynamic load dynamic load when the bearing ring or the washer relative rotation ( Radial or thrust bearings) Or when the rolling elements in rolling direction ( Linear bearing) , the effect on the bearing load. 2. Equivalent load theory of the equivalent load calculation load in general terms, in particular places, bearing under the effect of the theory of load as if under the theory of load. 3. The radial ( The axial) Basic static static load rating, basic radial ( 轴向) The load rating and total rolling element and raceway for deformation of the corresponding radial static load ( Axial static load center) 。 Assuming that under zero load, roller and raceway ( Roller bearings) For or assumption for normal bus ( All contact) , under the maximum contact stress, the rolling element and raceway contact point of total for deformation of roll diameter of 0. 0001 times. For single row angular contact bearings, radial load rating for provoking bearing ring each other purely radial displacement of the weight of radial load. 4. The radial ( The axial) The basic dynamic load rating, basic dynamic radial ( 轴向) The load rating constant radial load ( The center of the constant axial load) , under the load, the rolling bearing can withstand 1 million turn theoretically the basic rating life. For single row angular contact bearings, the radial load rating as a bearing ring of the weight of the each other purely radial displacement of the load. 5. Life ( Refers to a set of bearing) Life of the bearing ring or a washer or a rolling element material for the first time to present the tired before expansion, a ring or a washer related to another ring or a washer revolutions. Life can also be used in a given constant speed operation hours. 6. Start torque starting torque to a bearing ring or the washer relative to a fixed ring or washer torque required to start spinning. 7. Rotary torque running torque when a high temperature bearing ring or washer rotating, prevent another ring or washer movement required torque. 8. Radial radial load bearing the load acting on the vertical axis direction to load. 9. Axial load axial load effect to the bearing axis line direction of load. 10. Static load static load when the bearing ring or washer relative rotation speed is equal to zero, Radial or thrust bearings) Or when no movement in the rolling direction rolling components ( Linear bearing) , the effect on the bearing load. A: cause high temperature of motor bearing what is the basic reason of the next article: you have the status of the cracks of bearing steel ball
